SW40VE + TLR-2s = No Holster?

I'm scrouring the web in search of a OWB (or IWB) holster capable of accomodating the Sigma SW40VE with a Streamlight TLR-2s attached.

When I'm NOT using the light/laser I remove the S&W/Picatinni converter and holster in a Blackhawk Serpa made for the MP .40/9mm that works flawlessly.

Blade-Tech however hasn't been able to provide me with evidence that the Sigma will work with their "light capable holster (http://blade-tech.com/Weapon-Tactical-Light-Holster-w-Paddle-pr-967.html)" for the S&W MP .40/9mm based on an inquiry email I sent. Their reply was "No, it won't work and we don't have support for your gun at this time." Results from my magic 8 ball report "Outlook not so good!" :scrutiny:

Does anyone know of/use a holster setup that will work for this situation? The search results of this forum turned up no good results.
